Welcome back to boat season with the run on aspirin.
I have an annoying problem that has existed since I purchased my Catalina 30 five years ago. It is powered by an M 18 Universal that has an Oberdorfer fresh water cooling pump on it. The pump is bolted to the block by a flange with two hex head bolts on the starboard side of the engine.
I find that the v belt rubs on one of the hex heads and it wears about 1/8 of an inch because of the contact. I have called many techs on this problem and spoke to them so many times that I recognize their voices.
I cannot figure this one out and neither can they. The belt my sit high up in the pulley but I cannot find a thinner belt to use.
I thought of grinding the hex head down 1/2 way or, in the alternative, grinding off an 1/8 inch off the thickness of the flange. I fear, however, that I will compromise the strength of the bolt if I have to take it off or, in the alternative, weaken the flange.
I also considered replacing the hex head with a set screw with the same dimensions but I was told that it may not be possible to tighten it up properly against the block.
Has anyone experienced this same phenomenon and if so, what did you do to correct it?
